R: How to separate string in a cell into several cells in a row?

问题

I have following data

Data <- data.frame(
X = ("123 234 345 456","222 333 444 555 666" )
)


Data
#        X    
# 123 234 345 456 
# 222 333 444 555 666

A String in one cell, and the length of string is not same in each row

I want the following result

>Result
#    X    Y    Z    A    B
#   123  234  345  456  
#   222  333  444  555  666

one word in one cell

Can anybody help?

回答1:

strsplit is not required here. read.table should work fine. Try:

read.table(text = as.character(Data$X), header=FALSE, fill=TRUE)

You will have to rename the resulting variable names though.
